Writing group lets us talk and listen (7)
I believe the answer is:
handset
'us talk and listen' is the definition.
I can't tell whether this definition defines the answer.
'writing group' is the wordplay.
'writing' becomes 'hand' ('hand' can refer to someone's handwriting).
'group' becomes 'set' (both can mean a collection).
'hand'+'set'='HANDSET'
'lets' acts as a link.
Can you help me to learn more?
(Other definitions for handset that I've seen before include "controller" , "part of phone" , "Part of a telephone" , "Phone receiver" , "Shed tan (anag.)" .)
